Title: On an exact sequence relating the combinatorial anabelian geometry of hyperbolic curves

Abstract: Roughly speaking, the combinatorial anabelian geometry of hyperbolic
curves is a theory which discusses the relationship between the dual
graph of a stable curve and various associated profinite fundamental
groups of the stable curve. This theory gives a geometric description
of profinite surface groups. In this talk, I survey the combinatorial
anabelian geometry of hyperbolic curves, and discuss an exact sequence
relating this theory.
